AUTOMATIC RESERVOIR FORQVOLATILE OILS.

SPECIFICATION forming part of Letters Patent No. 250,041, dated November22, 1881.

Application filed March 7, 1881.

To all whom it may concern:

Be itknown that I, HERMAN FRITZ,of Cleve land, in the county of Guyahogaand State of Ohio, have invented a new and useful Improvement inAutomaticReservoirs for Volatile Oils, &c.; and I do hereby declare thatthe following is afull and exact description of the same, referencebeing bad to the accompanying drawings, and to the letters of referencemarked thereon.

This invention relates to certain improvements in reservoirs orsupply-vessels for that class of stoves or lamps in which the volatilehydrocarbons such as naphtha, gasoline, and the like-are to be burneddirectly for the pro duction of gas or light, or to be converted intovapor to be burned for such purposes. In the use of such hydrocarbonsaccidents are liable to happen, owing to the volatility of the materialemployed, and the liability of the formation of combustible vapors,which are apt to escape from the reservoir or supply-vessel, and where alight is contiguous to the same establish a communication between thelight and reservoir, which will result in an explosion in most cases,asthereservoir,upon beingemptied, takes in a proper equivalent ofatmospheric air. Such accidents almost invariably occur in filling thereservoir or supply vessel while the burners are lighted, the enteringliquid in such cases forcing out the collected vapor in thereservoir,which, by its specific gravity, falls to the burners below,and, becoming ignited, communicates the flame to the interior of thereservoir or vessel and explodes the contents.

The object of my 1nvent-1on is to obviate the danger above mentioned byso constructingthe reservoir or supply-vessel that when it is requiredto fill it it will necessitate its removal from the pipes leading tothe. burners, while such removal will automatically close theeduction-passage of the liquid and open the fillingaperture at the topsimultaneously, and vice versa when the reservoir or vessel is securedin place.

My invention consists in the combination, with the reservoir for holdingand supplying volatile oils to the pipe communicating with one or moreburners, of a nozzle or part containing the oil-supplying orifice,having a socket (Modeh) provided at its top with a recess forming adrip-cup, said nozzle extending below the res ervoir, as hereinafter setforth.

The invention also consists'in the combination, with a reservoir forholding and supplying volatile oil to a pipe communicating with one ormore burners, and having suitable feet or a suitable base for sustainingit in a vertical position when detached for filling, of a nozzle or partprojecting through the reservoir, provided with an oil-supplying orificeand a socket forming a drip-cup, all as hereinafter shown and described.

In the drawings, Figure 1 represents a vertical sectional view of myinvention. Fig. 2 is a top view. Fig. 3 is a view of the coupling andflange detached from the reservoir. Fig. at is a top view of thecoupling by which the reservoir or vessel is connected tothe tubeleading to the burner or burners. Fig. 5 is a side elevation of thevalve and valve casing and rod for operating the valve, a portion of therod being shown as broken oft"; and Fig. 6 is a perspective view of thecoupling which connects the reservoir with the supply-pipe.

The letter A indicates the reservoir or supply-vessel, which may beconstructed of metal or other suitable material, of cylindrical or anyother desired shape.

B indicates a valve-casing, which is made in the form ofa hollow conicfrustunnwith a flange, O, which may be secured to the edges of thecentral opening at the bottom of the reservoir or vessel by any suitablemeans that will form a liquid-tight joint. The said flange is providedwith downwardly-exteuding shouldered lugs D, the shoulders of which areadapted to engage the inclined or cam flanges E on the coupling F. whichis connected to the tube Gr, leading to the burner or burners.

The letter H indicates a valve, which, in the present instance, is inthe form of a conic frustum, and is adapted to fit and turn within thevalve-easin g B. The valve projects through the bottom of the vessel andan openingin the flange O, and terminates in an angular extension, at,which may be a portion integral with the valve, or may be a nut fixedthereon by a suitable key-fastenin g. This extension or prolongation ofthe valve, which may be termed a nozzle, has its seat in a seat, 1),formed in the coupling, with a suitable packing,c, interposed betweenthe end of the said extension a and seat b, in order to form a closejoint and prevent the escape of oil or gas. The coupling is furtherprovided with a concavity or recess, (1, in order to form a drip-cupthat is to collect and retain any oil that may escape from the interiorof the reservoir while detaching it for thepurpose of charging. The saidvalve is also provided with a vertical passage, H, and a transversepassage, I, the latter being so constructed and arranged that it can bebrought into connection with a transverse passage, K, through the wallof the valve-casing. It is preferable that the opening in the valve belonger than the opening in the valve'casing, so as to insure a fullcoincidence between the two openings without special observance of theoperator. The said valve has connected to it a vertical rod, L, whichextends upward through the top of the reservoir or vessel A, and isrigidly secured to a suitable plate or semicircular cover, M, which, inthe present example, is seated on the top of the reservoir, and isadapted to partially rotate thereon, being limited in its movement by asuitable stop or stops. The said cover M is located within a cylindricalchamber, N, at the top of the reservoir A, and is so arranged as tocover the opening through which the rod L passes, and cover and uncoveran aperture, P, in the top of the reservoir as it is moved by thevertical rod, as more fully hereinafter specified. The apertureP isprovidedwith down wardly-turned edges,which form a seatfora float-valve,R, which is located in a perforated or slotted cylinder, S, extendingdownward from the top of the vessel A to near the bottom. The saidcylinder communicates with the reservoir through the perforations orslots, and thus forms a passage for the introduction of the liquid withwhich the reservoir is to be charged, being adapted toreceive the liquidfrom the chamber N, through which the apparatus is filled, the saidchamber being provided with a removable cap, T, for the purpose. Thevalve it is provided with a valve stem, U, which passes loosely upthrough a tube, V, in the top of the vessel, and through the removablecover of the reservoir, in such manner as to guide the valve in itsmovementand close itagainst the downwardlyturned edge at the aperture P,and thus close the reservoir or vessel when filled.

The operation of my invention is as follows: In its normal condition, orwhen filled, the reservoir or casing will be in position as indicated inFig. 1, withthe horizontal passage in the valve in conjunction with atransverse passage in the valve-casing, which will permit the liquid toflow freely to the burner. WVhile in this position the inclined flanges,bearing against the depending lugs on the flange of the valve-casing,will keep the coupling securelyin its seat and form a liquidtightjoint.

While the communication is thus established below, the cover will closethe filling-aperture at the top. When it is desired to recharge thereservoir, after becoming empty, in order to open the filling-apertureit will be necessary to turn such reservoir untilthe cover has passedaway from such aperture. This closes the valve below and releases thereservoir from the coupling, necessitating its removal from the vicinityof the burners during the operation of charging, and thus obviating alltendency to accidents and to enable the reservoir to maintain itself inan upright position when detached and removed from the supply tube orpipe, it is provided with suitable supports or legs.

1 do not claim in this application, first, combining with the reservoiror supply-chamber of a vapor stove or lamp a valve-casing and a valvehaving an annular prolongation extending through the bottom of thereservoir, the depending legs, and the coupling having inclined or camflanges adapted to be secured to the valve by the lugs, whereby thevalves will be automatically opened in the act of applying the reservoirto the coupling and closed when detaching therefrom; second, combiningwith the reservoir, its valve-casing, and valve having an angularprolongation, the depending lugs and coupling, the vertical rod andcover, the latter being adapted to open and close a filling-aperture atthe top of the reservoir; third, combining with the reservoir, itsvalve-casing, and valve having an angular prolongation, the dependinglugs and coupling, the vertical rod and cover, the latter being adaptedto open and close a filling-aperture at the top of the reservoirsimultaneously with the closing and opening of the valve below; fourth,combining with the reservoir the valve having an angular prolongationextending beyond the valve-casing, the rod for operating the valve, andthe detachable coupling having an angular socket and a concavity orrecess to form a drip-cup; fifth, combining with the reservoir thechamber arranged on the top thereof to serve as a funnel for filling thereservoir, and an inclosure for the plate that covers the filling-tubeand the opening through which the valve-rod passes, said chamber beingprovided with a cover having an opening through which the rod of thefloat passes. These features are made the subject of an application forpatent filed by me June 17, 1881; but
